Studies on the Effective Principles of Digenea simplex Aq. I

Separation of the Effective Fraction by Liquid Chromatography

Abstract

Digenic acid, m.p. 251° (decomp.), [α]_D²⁴: -14.8°±0.5° (c=1.01, H₂O), C₁₀H₁₇O₅N, and digeneaside (sodium mannosidoglycerate), m.p. 261° (decomp.), [α]_D¹⁰: +94.0°±0.5° (c=3.00, H₂O), C₉H₁₅O₉Na⋅H₂O, were isolated from Digenea simplex Aq. The acid was found to have an anthelmintic action.
